Petrol Head?

You know you are a petrol head when
Something falls off of your car, you wonder how much weight you just saved.
You thoroughly enjoy showing the tailgater behind how to drive around a highway off-ramp.
You walk proper lines through the grocery store.
You drift your shopping cart around the isles.
Exasperated, you've been known to yell "It means 'check your mirrors!!" at your television.
You buy new parts because you don't know where you put the spares.
You look at the purchase of tools as a long term investment.
You have enough spare parts to build another car
After your answer to "What did you do this weekend?" the next question is always: "And you do this for fun? Right?"
You talk to other cars on the road, calling them by the manufacturer's name.
Your criteria for selecting a significant other include auto repair skills. Air tools optional.
You complain when cars in front of you on highway off or on-ramps don't stay on the line, causing you to scrub speed before the apex.
You refer to the corner down the street from your house as "Turn One."
You look at the fire hydrant at that corner and see an apex marker.
You always late apex the intersection and try to pass a few cars coming out.
Everywhere you go, you try to find the fastest line through the turn.
You think that traction control and ABS are for those who can't drive.
You save broken car parts as "mementos".
Your last several motorway forays included just brushing the curbs as you apexed the on-ramps perfectly.
The shop manager at your local car dealer mutters "dear Lord" under his breath every time he sees you.
You would choose a rollbar over air conditioning if it were an option.
You know the "racing line" of every turn in your daily commute, including your alternate routes, and practice hitting them every day.
You tell whom ever happens to be driving you around, 'you know you missed that apex right?'.
And finally, no matter where you are going the drive is more exciting than the destination..
